Why Designers Choose the Seeley Cube

The Seeley Cube is the foundational choice for anyone who appreciates clean, minimalist geometry. If you have ever seen a standard plastic planter warp or fade after a single season, you will appreciate the industrial-grade difference here. It is designed to be a permanent, design-forward extension of your architecture.

In professional settings, these are most often used to create a "ceremony of arrival" at entryways or arranged in a rhythmic series to create a "living wall." Because the lines are so crisp and the matte finish so refined, the Seeley Cube defines space—like an open-plan office or a sprawling patio—without adding visual clutter. It anchors the environment, allowing your greenery to take center stage.

The Science: Why Steel-Reinforcement Matters for Large Planters

Most large planters suffer from "bellying"—a phenomenon where the sides bulge outward once filled with heavy, wet soil. This ruins the architectural silhouette. To prevent this, NMN Designs integrates internal steel reinforcement into our 20", 24", and 30" models.

This engineering ensures that even when housing a heavy, mature tree, the walls remain perfectly plumb and vertical. Combined with our commercial-grade fiberglass, you get a vessel that handles extreme thermal expansion (from scorching summers to sub-zero winters) without the cracking or brittleness found in standard resin or plastic pots.

Engineered for Performance: Indoor and Outdoor Versatility

The Seeley Cube transitions effortlessly between environments. For interior use in a foyer or gallery, keep the rubber plugs inserted for a watertight seal. For outdoor installations on a deck or patio, simply remove the plugs to ensure vital drainage and oxygen for the root zone.

Recommended Tree and Plant Pairings by Size:

  • 14" Cube (Medium): Ideal for architectural foliage and "tree-like" indoor plants. Best for Snake Plant, ZZ Plants, or a Spider Plant. Perfect for office corners or flanking a residential console table. Outdoor - Ornametal Grasses, Small Plants.

  • 20" / 24" Cube (Large and Extra Large): The perfect size for entryway ceremony and ornamental trees. Ideas include Evergreens and Boxwood Topiaries, Ornamental Grasses, Olive Trees, or Fiddle Leaf Figs. For a vertical architectural look, Sky Pencil Hollies are excellent.

  • 30" Cube (XXL -Extra-Large): Designed for specimen trees and high-impact privacy. This volume is required for larger trees such as Japanese Maples, Dwarf Citrus (Lemon/Lime), or Serviceberry. To create a privacy screen, plant a series of Emerald Green Arborvitae or Tall Ornamental Grasses.

Pro-Tips for the Best Results

  • High-Wind Stability: For exposed roof decks or coastal balconies, add 3 inches of heavy gravel at the base before adding soil. This lowers the center of gravity, ensuring your privacy screen stays upright during heavy gusts.

  • Thermal Protection: While the fiberglass is frost-proof, using an insulated liner inside the planter in extreme northern climates can help protect the root balls of perennial trees, ensuring they return season after season.

    Wonderful product
    Color: Brown, Number of Items: 1, Color: Brown, Number of Items: 1
    This chair offers good lumbar support and a well-padded seat. It has a very nice and smooth rocking motion, you can loosen the tight/loose knob for reclining, and it is very comfortable to sit in while working on the computer or relaxing to watch TV. The back of the chair hits just above my neck, so the back of my head rests comfortably on the top of the chair. The color, brown, is exactly what I expected and looks professional. The height adjustment works well, it sits higher than my old chair, and I like that. It seems sturdy for the 300-pound weight recommended. I got it on Prime Day, so it was a good value for the money. It came packed well and quicker than expected. The pictures are a comparison to my 20-year-old office chair. Assembling the chair was easy, however, be sure to attach the bottom part of the chair with the tight/loose knob facing the front of the chair. It's not clearly marked on the instructions. When it came time to put the back of the chair on it would be good to have another person to hold the chair back for you to align the chair arm holes and screw in, then you should be OK but I did discover that if I had attached the arms to the back of the chair first, it would be so much easier to align them for attachment. The wheels glide very easily and will take you across the room after one push. It swivels at 360 degrees easily, almost making me dizzy. I am writing this review the same day I got the chair so I will update if I run into any issues. Otherwise, I recommend this chair.

    So far, so good
    Color: Black, Number of Items: 1, Color: Black, Number of Items: 1
    When Covid hit early 2020, I was sent home to work remotely for the first time in my working life. However, my old chair that is pictured on the right is about 25 years old and no longer has any butt cushion. It quickly became painful to work in that chair all day. I have since moved to a new state and found a remote job I will be starting soon so I decided it was time to upgrade the chair. This is a decent chair if you are on a budget like I am and you are not hard on your stuff adding premature wear and tear. For me, it has good lumbar support which I needed, and more cush for the tush! I am a proportionate 5'2" female and about 125 to 130 pounds. The seat has just enough room for my butt but I don't think I would recommend this for larger people. I would look into sizing up to the big and tall chair. Take note of the seat and back size to know what would work best for you but this chair feels small yet good sized for me only because I was able to go by the measurements of my old chair. Might even be best for you to go into an office supply store to test out chair sizes for comfort before making a purchase. Sometimes I like to sit criss-cross applesauce and this chair has a very nice and smooth rocking motion after loosening the tight/loose knob for reclining and is so comfortable for me that I may fall asleep on the job and get fired. The back of the chair hits just above my neck so I am able to tilt my head back a bit to let it rest since my upper back and neck sometimes go numb after sitting for too long. Ugh, it's just so much fun getting older!! Assembling the chair was easy until I got to step 4 to put the back of the chair on. If you have another person to hold the chair back for you to align with the chair arm holes and screw in, then you should be OK, but since I had no one to help, I had to take the seat off and lay it down. I still struggled to align the back while the arms were attached to the seat so I removed the arms from the seat and attached them to the chair back and then aligned the seat with the arms and screwed them in. Once done, I inserted the completed assembled seat, chair back, and arm attachments back onto the wheels. The wheels glide very easily and will take you across the room after one push. I am writing this review the same day I got the chair so will update if I run into any issues. Otherwise, I recommend this chair.

    Comfortable but lack of back support on this chair
    Color: Black, Number of Items: 1, Color: Black, Number of Items: 1
    I give this chair a 4 star not a 5 star review. Reason for that if you look for the first picture I pst you can see from the back of the chair how it reclines. There is no adjustment to make the back rest come up straight so when your working all day at the desk you is an upright right position. I have to put a pillow behind my back for support cause while working leaning back is uncomfortable and who wants to lean back while working. so there is a lack of back support. .Great gaming chair for that reason. Though I really like the looks and the color of the chair. The material was very soft and the quality was made well. The chair you can make go up or down for the height which is nice. The ability to be able to move the char around while sitting is a plus and the wheels move smooth and with ease. I had to put this together which was simple to do and came with everything I needed when open the box. So before buying if the back support and leaning back isnt an issue for you then this would be the perfect chair for you. Please not the first picture with the darker rug is the chair I got , second picture isnt mine but for a review that their chair was up straight. Isnt the way mine should have come. I didnt questioned or return it because it was so heavy and bulky to take back to a UPS store. I just kept it because everything else was great.

    Great price and Quality
    Color: Khaki, Number of Items: 1
    Best money ever spent on an office chair. At the time of purchase, it was less than half the price of local retail stores. Once we received it and put it together, it was top notch. Better than expected. Now time will tell how long it stays that way. Very comfortable, strong material, and easy to adjust.
